Flood Factor™ FAQ (2024)

FAQs

Is flood Factor legit? ›

The First Street Foundation National Flood Model and the Flood Factor tool were created by the First Street Foundation, a non-profit with a team of over 80 scientists, technologists, and analysts. The model is publicly available and peer reviewed.

Flood Factor™ provides comprehensive flood risk information for each individual property, including a score ranging from 1 (minimal risk) to 10 (extreme risk) as determined by the cumulative likelihood and potential depth of flooding over the next 15-30 years.

A property's Flood Factor is determined by its likelihood of flooding and the potential depth of that flood. Because flood risks accumulate over time, it specifically looks at the likelihood of 1 inch of water reaching the building footprint of a home at least once within the next 30 years.

The nearest flood zone is 1/3 mile away, adjacent to a creek. However, the website floodfactor.com rates this house at a 7/10 flooding risk, 1 being the lowest. They estimate a 50% chance of flooding in 10 years and 98% chance in 30 years.

Disadvantages of the Program

The program had to pay out more money than it was able to take in. This is one reason why it is difficult to get private flood insurance.

Properties with at least an 80% chance of flooding over 30 years will have a Flood Factor of 5 or higher. Properties with at least a 99% chance of flooding over 30 years will have a Flood Factor of 6 or higher.

The Flood Model's methodology was reviewed by experts in the field, who confirmed its scientific rigor and deemed it worthy of scientific publication. Flood Factor simplifies flooding so every American can determine their risk, understand the science, and make informed decisions to prepare for the future.

Calculate the 'Wetted Perimeter (m) of the channel by using Pythagorean theorem at each channel section as illustrated in figure on the right. Calculate the 'Cross-sectional Area (m²)' of the flood flow by multiplying the width of each section and the average flood water depth of each section.

What is the flood risk method? ›

Flood risk assessments focus on four main components: Flood hazard—the probability and magnitude (e.g., depth, velocity, discharge) of flooding. Exposure—the economic value of assets subjected to flood hazard. Vulnerability—the relationship of flood hazard properties to economic loss.

First Street Foundation is a 501(c)(3) nonprofit research and technology organization working to define America's flood risk.

What does flood factor 9/10 mean? A flood factor 9/10 means that your home has a 99% chance of experiencing one inch or more of flooding over a 30-year period. While this is important to know, flood factor is not used by the NFIP to determine flood insurance rates.

Calculate flood risk

Risk = Likelihood × Severity Multiply your mean likelihood and mean severity scores together to give a flood risk score for each zone.

Predicting floods is notoriously tricky. They depend on a complex mixture of rainfall, soil moisture, the recent history of precipitation, and much more. Snowmelt and storm surges can also contribute to unexpected flooding.

Public goods include knowledge, official statistics, national security, common languages, law enforcement, public parks, free roads, and many television and radio broadcasts. Flood control systems, aids to navigation, and street lighting are also common social goods.
